State which of the following sets of order pairs represent a function
Tamiku [17]

Remark

The quick answer is C does not represent a function. It has two y values for x = 2. These two points are (2,1) and (2,3). That eliminates C. No x can have 2 y values and be called a function. A function can have many x vales for a single y and still be a function.

A has all different x values, so it could be classed as a function. There are no values where x has more than 1 y value.

B also has all different x values. It too is a function.

Answer

A and B are both functions. C is not.

Simplify this algebraic equation: 3y - 7(5x + 2y)
Taya2010 [7]

Answer: -11y - 35x

Step-by-step explanation:

This problem utilizes the Distributive Property of Multiplication.  It states that: a(x + y) = ax + ay.

Thus, utilizing this property (distributing -7), change the equation into:

3y - 35x - 14y

Then, simply combine like terms to get:

-11y - 35x

Hope it helps :) and let me know if you want me to elaborate.

Dominique needs to solve the system of equations by graphing. Which statement is true about the system? 2 x minus 3 y = 12. Y =
Nutka1998 [239]

Answer:

Option C) The first equation is y= 2/3x-4 when written in slope-intercept form .

Step-by-step explanation:

We have

2x - 3y = 12  \:  >  \: first \: equation

The first equation is in Standard form .

Convert to slope Intercept form .

Isolate the Variable y .

3y = 2x - 12

Divide by 3 both sides .

y =  \frac{2}{3} x - 4

y =  -  \frac{3}{5} x + 2 > second \: equation

The second equation is in slope Intercept form .

Convert to standard form

Multiply by 5 both sides to remove the fraction .

5y =  - 3x + 10

3x + 5y = 10

<h3><u>Verify each statement :- </u></h3>

<h3>• case A) Both equations are in slope-intercept form.</h3>

  • False

  • Because only the second equation is in slope -intercept form

<h3>• case B) Neither equation is in slope-intercept form .</h3>

  • False

  • Because, the second equation is in slope -intercept form

<h3>• case C) The first equation is y= 2/3x-4 when written in slope-intercept form</h3>

  • True (see the procedure)

<h3>• case D)The second equation is 3x+5y=10 when written in slope-intercept form.</h3>

  • False

  • Because, the second equation is 3x+5y=10 when written in standard form .

15 points!! Please help! please explain how you got you answers
Lynna [10]

We observe that a line will pass through 3 points, but to find a slope we only need two.

We see that it passes through points (assuming the scale of graph is 1 : 1) P_1(x_1,y_1)=P_1(0,1) and P_2(x_2,y_2)=P_2(2,-1).

We can use slope formula that applies for any line and produce the same slope for any two different points on the line

m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{2-0}=-1

So the slope is -1 also it intersects y-axis at n=1 so the general form of the linear function is

f(x)=mx+n

That is in your case

\boxed{f(x)=-x+1}

Hope this helps.
